Latest version for bootstrap 3 fixed for version 2.1.9 and posted on e107.org
Freelancer theme for e107 is originally based on free Onepage HTML version from startbootstrap.com. This template has the same name Freelancer (Freelancer is a one page Bootstrap portfolio theme for freelancers.)
You can see and compare HTML demo here: https://startbootstrap.com/template-overviews/freelancer/
Demo of e107 version 2.0.3 is here: https://themes.e107.org/freelancer/
It was ported and customized for version 2.1.5 two years ago. Customization changed one page HTML template to multi-page version so you can fully use advantages of e107. It was thanks combination of one page scrolling with standalone pages. Last stable version with bootstrap 3 is version 2.0.4 tested with version 2.1.9 (2.2.0 git).
Latest stable version for bootstrap 3 is version 2.0.4 compatible with 2.1.9. There will be no update of this version.
Because there is already available bootstrap 4 HTML version, there is no need to update this theme for bootstrap 3. So next version will be based on with bootstrap 4.
I personally don't use this theme, I don't know anybody who uses it, so this can wait.
